I learned about this product when a beauty consultant on Suzykirei recommended the serum. I was intrigued by the unusual starfish ingredient, but was a little skeptical as it was unfamiliar and I wondered if it would really be effective. So I decided to try the pack out first! After using it, I decided I'd like to use it again, and I'd also like to buy the serum as well! The pack is a unique, stringy liquid with a texture that soaks up the skin! After removing the pack, my skin felt lighter and not sticky, as you'd expect from a thicker pack, and it felt like it had absorbed moisture into the skin! After using it once, I felt like my skin texture had improved and my pores were less noticeable! The beauty consultant who recommended it said that the effects vary from person to person, but in her case, she especially noticed brighter skin!
It costs about 1000 yen per sheet, so it's hard to buy, but the feel is amazing. I'll use it on special occasions!
It was also moisturizing and felt good.
I bought this after being recommended by a staff member at Suzykirei. It contains starfish extract, which I've never heard of before, so I wanted to try it. I plan to use it the day before an important event.
